A housing for a microtome which is capable of being employed in a cryostat. The microtome housing includes a waterproof microtome chamber having an elongate slot formed in the wall thereof through which an object holding device extends. The elongate slot has a seal disposed about its periphery and the slot is covered by a coverplate which is provided adjacent to the seal. The coverplate is rotatable about the axis of a pin which is provided on the interior of the chamber wall. The chamber further includes magnets which are arranged on the wall of the chamber adjacent to the elongate slot such that the magnets retain the coverplate over the elongate slot. This arrangement allows the object holding device to be easily inserted into and removed from the chamber, while at the same time maintaining substantially moisture free conditions within the chamber.
